In addition to dairy and breads, it is frequently used in canned fruits, batter mixes, and other packaged and preserved foods where mold can occur. In these cases small amounts of liquid or crystalline propionate are usually added to cans, boxes, and packages just before they're sealed. The additive doesn't have a taste and doesn't usually impact the overall quality of the food, aside from preventing spoilage.
